We have a small quandry on the Launchpad development team at the moment. As bug 268508 discusses, when one searches for a bug on Launchpad we do a substring search on the names of bug targets.
For instance, searching in Ubuntu for ‘gcc’ will return all bugs on the packages ‘gcc’, ‘gcc-4.4′, ‘gcc-4.3′, ‘gcc-3.3′ and so forth. Likewise search for bugs in a project group will do a similar substring search on each of the individual projects in the project group.
It turns out that doing this search is itself expensive. I asked on the Ubuntu devel list about turning it off. We would close bug 268508 and also significantly improve search performance.
However this is a possibly contentious change – there was one mail strongly in favour of the current behaviour – so I’d like to get this change proposed to a wider community.
If you’ve got a strong opinion – that the current behaviour is good, or like bug 268508 describes, that its a poor behaviour and we would be better off without it, then I’d love to hear from you. Just leave a comment on this post, drop me an email – robert at canonical.com – or post to the launchpad-users mailing list.
